PET (Polyethylene terephthalate Copolymer – natural and black colour)
Universal structure material with both characteristics of PA 6 and POM: dimensional stability and high stiffness, high chemical resistance and low friction coefficient. The material is used in production of precise structural parts. The parts are heavy-duty and they do not demand any external lubrication in the humid environment or they work in the environment of low thermal expansion indicator.
Use:
- Elements working in humid environment
- Electroinsulating parts in electromechanics
- Elements working in acid or alkaline environment
- Gears with low modules
- Guide rails and guides
- Highly loaded rolling and sliding elements
Characteristics:
- Perfect resistance to contamination
- High resistance to creep
- Very high stiffness and hardness
- Very high chemical resistance (higher than POM and PA6)
- Good machinering properties
- Low friction coefficient
- Low coefficient of linear expansion
- Good ductility
- High dimensional stability (better than in polyacetal)
- Physiological safety
- Low resilience (lower that resilience of POM and PA6)
